EMERY STERHARIDT, OF NEW YORK, N. Y.

TENT.

Specification of Letters Patent.

Patented Dec. 23, 1919.

Application filed April 30, 1919. SerialNo. 293,675.

-.To all whom it may concern.

Be it known that I, EMERY STERHARDT, a citizen of Hungary, and a resident of New York, in the county of NewYork and State of New York, have invented certain new and useful Improvements in Tents, of which the foll owing is a specification.

The present invention relates to tents, and more particularly to folding or collapsible tents. 5 Y The main object of the invention is to provide a tent of very simple construction, which can be quickly set up, which is rigid and'stable .and yet can be quickly taken down andi folded in small compass for transportation.

With these and other objects in view, which will more fully appear as the nature of the invention is better understood, the same consists in the combination, arran ement and construction of parts hereinafter described, pointed out in the appendedolaims and illustrated in the accompanying drawings, it being understood that many changes may be made in the size and proportion of the several parts and details of construction within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the invention.

One of the many possible embodiments of the invention is illustrated in the accomtie I the corner-posts of the tent, there being four b panying drawings, in which Figurel 1s a""perspect1ve view of a tent constructed in accordance with the present invention; Fig. 2 is a front elevation of the .tent frame in extended state; Fig. 3 is a top plan view thereof; Fig. 4 is a front elefvation ofthe tent frame, the elements being shown in their folded positions; Fig. 5 is a vertical section taken through a portion of one of the frame posts, showing the manner of holding together the telescoping sections thereof Fig. 6 is a section taken on line 66 of Figp2, on a larger scale; Fig. 7 is a sec tion taken on line 77 of Fig. 2, also on a larger scale; Fig. 8 is a section taken on line 8-8 of Fig. 2, also on a larger scale; and Figs. -9 and 10 are perspective view of details of construction of the tent frame.

In the drawings, the numerals 10 indicate of the same, all of which are alike in construction. Each of these posts comprises a plurality of telescoping sections, in the present case three, denoted, in their order, by the numerals ll, 12 and 13. To prevent disengagement of these sections, the same are provided with stops, in the form of rings 14 and 15 (Fig. 5), which are secured in any suitable manner to the inner and outer faces, respectively, of each two adjoining post sections, thereby not only serving as the means for preventing a disengagement of the same, but also for maintaining the sections in concentric relation to each other. In order to keep the post sections in their extended positions, spring catches 16 are provided. Thesecatches are each made in the form of a blade spring 17, that is socured, for instance, by a screw 18 to one of two adjoining sections and carrying at its free end a lug 19, adapted to project into an aperture 20 in the other one of said adjoining sections. These spring catches are disposed within the. posts, their lugs pro jecting outside the same so as to be easily manipulable.

The postsextend vertically, when the tent is set up, and are each of a length, when extended, that is somewhat higher than a fair-sized person. The four posts are disposed, when the tent is set up, in the corners of a square, and are spaced apart by upper side-bars 21 and lower side-bars 22, each set of side-bars forming substantially the sides of the square in the corners of which the posts are disposed. These side-bars extend horizontally, as clearly appears from the drawings. The upper side bars are ach made-of two sections 23 and 24, which are pivoted together at their inner meeting ends, as shown at 25. At their outer ends these side-bar sections are pivoted at 26 to brackets 27, the latter being fixed to the upper ends of the corner post sections 13. In order to hold the sections of the side bars in their extended positions, braces 28 are provided, each brace being pivoted at 29 to a bracket 27 and carrying at its free end a pin 30, which is seated in a slot 31 in the respective section of a si(lcba1'. The braces 28 are disposed above the said side-bars. To pre vent the inner meeting ends of the side-bar sections from moving upward, there is attached to one section a finger 32, that bears against the ,undorface of the adjoining sidear section.

The lower side-bars 22 are also made each of two sections, denoted by the numerals 33 and 34. These sections are pivoted together at their meeting ends, as shown at 35, at.

. their outer ends they being pivoted at 36 to brackets 37, the latter being fixed to the lower ends of the corner post sections 11, and more particularly adjacent the lower ends thereof. Braces 38 are provided, the latter'bein similar in construction to the braces 28 a ove referred to, they being pivoted at 39 to the brackets 37 and carrying at their free ends pins 40, seated in slots 41 in the respective sections of the side-bars 22. The inner pivoted ends of the sections of each side-bar are prevented from moving upward by fingers 42, which are fixed to one section and bear against the upper face of the other section. From Figs. 3, 6 and 7 of the drawings, it appears that each sidebar 21 does not register with the corresponding lower side-bar 22, but that the said corresponding side-bars are disposed in different planes, so as to permit a proper folding of the structure.

The roof of the tent is pyramidal and is made up of four bars 43, which are pivoted at 44 to a crown 45, that is disposed at the apex of the pyramid, their lower ends beingpivoted at 46 to the brackets 27 above re ferred to.v Into the crown fits a lug 47 to which is fixed a hollow dome-shaped body 48, that is disposed above the crown and overlies the same. To hold the dome-shaped body in position, a screw 49 extends into the lug 47, the head of said screw abutting against the lower face of the crown 45.

The fran'le is covered by a canvas 50, or other suitable covering, that is detachably fastened to the brackets 37, the body 48 keeping it in engagement with the crown 45.

, The tent may be of any suitable size, the one herein described being of one-man size, suited to shelter a person in standing position.

The operation of the device is as fol- 'lows:1n order to fold the tent, first the dome-shaped body 48 is removed from the frame thereof, after which the covering may be taken off. One of the pivots 46 is then.

disengaged from the corresponding bracket 27 and bar 43, whereby all of the bars 43 are permitted to move downward around the remaining pivots 46, when the four corner posts are brought close to one another. To

bring these corner posts as close to one another as the brackets 27 and 37 will permit, the pivoted meeting ends of the sections of the upper side-bars 21 are caused to move downward by swin ing the same around their pivots 26, and t e pivoted meeting ends of the lower side-bars 22 are forced upward,

by swinging the sections of the said sideis obtained, around which the canvas covering may be wrapped and secured in place by a cord or similar means.

In order to set up the tent, the operations now described are performed in the reverse order.

What I claim is 1. A tent frame comprising four corner posts, each made of a plurality of telescoping sections, a bracket fixed to the upper end of each innermost post section, a bracket secured to the lower end of-each outermost post section, side-bars connecting said firstnamed brackets, side-bars connecting said second-named brackets, each side-bar being made of two sections pivoted together at their meeting ends and at their outer ends to two bra .kets on corresponding post sections, each side-bar section being provided adjacent its outer end with a slot, a brace associated with each sidebar section ivoted' at one of its ends to the respective iiracket and carrying upon its other end a pin in engagement with the respective slot, a roof bar pivoted to each of said first-named brackets, and a crown connecting said roof bars.

2. In a tent frame according to claim 1, each corresponding set of upper and lower sidebars being disposed in parallel spaced vertical planes.

Signed at New York, in the county of New York, and State of New York, this 26th day of March, A. i). 1919.
